[R] Obtaining Least Square Means with lme (mixed models)
Hi Dear Alex, A few years ago you sent this email to R list: Hello, I was wondering how one could obtain LSM for fixed factors in a mixed-effect model using lme. In other words, if I have model such as: model<-lme(yield~period+treatment+period*treatment, data=data,random=~1|cow) how can I get LSM for period, treatment and their interaction? Thanks a lot! Alex What was the response?? I have the same question! Thanks! -- Claudia Ceballos Ph.D. Candidate, Department of Ecology, Evolution and Organismal Biology 253 Bessey Hall, Iowa State University, Ames, IA 50011 http://www.public.iastate.edu/~ceballos/
